How to Troubleshoot the Rigid PVC Process

Look under each sink for a water leak in the cold or hot water line. Inspect each connection closely with a flashlight. Shut off the valve if the water leak is coming from one of these lines.

Crawl under the house with your flashlight and rag. Inspect each rigid PVC line, joint and valve. Rub the rag around the joint to see if it gets wet or damp. Turn off the main shutoff valve if the leak is discovered under the house.

Look for the main water line that runs into the house. Crawl out from under the house and walk around to the place where the main line enters the home. Stick your rod in the ground and check to see if the ground is soft. Walk along the water line and periodically stick the rod into the ground to see if it is soft. Leaking PVC lines will push water to the surface, making the ground damp.

Walk along the irrigation lines and stick the rod into the ground. Start at each sprinkler head and walk along the line back to the house or main sprinkler outlet. Turn off the main valve to the sprinkler system if this is where the water is leaking.

Dig up the ground with the shovel at every location you found soft or wet. Dig on the side of the pipe once it has been located. Leaking water will be seen flowing from the rigid PVC if this is the damaged section.
